Another object is to provide such a cap which'will be-sim le and cheap to manufacture and reliable in'service- Further objects will appear from the 01- 15. lowing description takcn'in connection with and with a generally cupped shape, as illustratedinEigurel, and having a top 1 and a downwardly extending, deep fflange 2.

being resilient, will grip the neck 5 of the container with sufficient pressure to retain.

constructed from glass tubing. Such tubing often varies considerably in size, and a close fitting cap may fit one size but fail to fit another. The cap of the present invention, having the gripping elements 3 resilient, provides extended bearings extending substantially the full depth of the flange and is adapted to fit containers or tubes of varying sizes within a certain degree of variations. Accordingly, a stock of one size of caps may be adequate to fit a complete line of containers in spite of the variation in the a size of tubing from which such containers can be made.

It will be noted that since the gripping elements are cut free of the flange 2 throughout their extent and since they are long, their resiliency is due to their own flexure and does not involve flexure of the flange 2. A wider range of sizes may thus be accommodated.

It is obvious that various changes may be made in the details of construction without departing from the spirit of this invention; it is to be understood, therefore, that this invention is not limited to the specific details shown and described.
